A new virus was found in Sauropus androgynus plants with curled and yellow leaves in China and tentatively named "Sauropus androgynus virus" (SaV). The complete genome of SaV is an 8007-nucleotide-long (+)RNA, excluding the 3'-poly(A) tail, and contains five open reading frames. Both pairwise comparisons and phylogenetic analysis of the putative replicase and coat proteins showed that SaV has a high level of sequence similarity to members of the genus Allexivirus of the family Alphaflexiviridae. This is the first report of an allexivirus in Sauropus androgynus.
在中国，人们在叶下珠属植物卷曲发黄的叶片中发现了一种新病毒，并暂时将其命名为“叶下珠病毒”（SaV）。SaV的完整基因组是一个长度为8007个核苷酸的（+）RNA，不包括3'-聚腺苷酸尾，包含五个开放阅读框。对假定的复制酶和外壳蛋白进行的成对比较和系统发育分析均表明，SaV与甲型柔性病毒科马铃薯X病毒属的成员具有高度的序列相似性。这是叶下珠中马铃薯X病毒属病毒的首次报道。
